OS X and transferring files (with Transmit)

In my last post I mentioned how one of my server hard drives died and I ended up purchasing a replacement. I had done some thinking on what I wanted to do with regards on how to utilize the new drive, and that ClearOS 7 was now available. I decided to use the new 3TB drive as added storage, and migrate some files. I wanted to merge my Plex media to one source instead of being spread over three drives like it was. To do this was very easy, just time consuming due to the amount of movies I needed to move, somewhere around 450GB worth. I didn’t even think of using the terminal and issuing a “mv” command as I am sure it would have been faster and this issue wouldn’t have occurred. I fired up Transmit FTP and opened two windows. One window was the old drive and the other the new. I simply drag and dropped the files, copying them, and let it run while I went to sleep. I awoke the next day to an error of no free disk space on my Mac Pro. WTF? Upon investigation I found that Transmit was caching the file transfers locally on my Mac. Thats just fucking stupid. So I’m assuming that you cannot transfer more files than you have free disk space, because apparently it will run your drive down and crash your shit.

A reboot will clear the cache (for Transmit) or you can manually delete the cache. Its located at:

There is a ton of other crap in there as well. Most of it should be safe to delete, it is just cache right?
